For inserted items we use the index (similar to startIndex in\nQUEUE_LOAD) and not currentItemId, because the itemId is unknown until\nthe items are inserted. If not provided, the currentItem value will be\nthe same as before the insertion (unless currentItemId is provided).\nThis param allows to make atomic the common use case of insert and play\nan item.\n\n### currentTime\n\n(number or undefined)\n\nSeconds since the beginning of content to start playback of the current\nitem. If provided, this value will take precedence over the startTime\nvalue provided at the QueueItem level but only the first time the item is\nplayed. This is to cover the common case where the user jumps to the\nmiddle of an item so the currentTime does not apply to the item\npermanently like the QueueItem startTime does. It avoids having to reset\nthe startTime dynamically (that may not be possible if the phone has gone\nto sleep).\n\n### customData\n\n(non-null Object or undefined)\n\nApplication-specific data for this request.
